* fixes for the Qt plugin compilation under Debian
* heavy butchering in the CSS and DVD ioctl code to put all architecture-
dependent code in dvd_ioctl.c
* added almost fully-functional /dev/dvd driver for MacOS X in
extras/DVDioctl; to build it:
% cd extras/DVDioctl
% pbxbuild
% kextload build/DVDioctl.kext # note: kextload has to be run as root
be aware that the license for the DVDioctl kernel extension is
not GPL but APSL, because I borrowed some code from the Darwin kernel.
